Test1 + test2
=============
Output files of this two tests show time of execution of can_send() function
measured by Ftrace function tracer.

Main algorithm of benchmark consists of running "cangen" command (with 
different parameters) on different qdisc + filter configurations and 
measuring time of execution of function can_send().

Testing set of test2 is identical to test1 besides the delay between each
sent frame -- test1 measures on packets sent in 1 ms interval while test2
on packets sent in 0 ms interval.
Absolute times (for each single test) measured in test1 and test2 differ
in some constant value (cca 12 us), but the relative change in time among 
each single test in a set is in test1 and test2 quite the same.

Observations:
* Classification with canprio (measured on P4 CPU) has negligible overhead.
* Processing of EFF frames takes longer than of SFF frames.
* Storing SFF rules in bitmap leads to much quicker classification 
  (difference grows with number of rules).
* Sending frames with "0 ms" delay leads to buffering them and storing into
  device after some periode (unlike sending in 1 ms interval sends 
  each frame separately -- i.e. communication with hardware because of each 
  frame).
